The only time I’ve ever had my food stolen was when I was working as a deckhand on a tug. I’ve been working white collar jobs for the past 25 years and haven’t had to deal with it since.
Also, my solution was to spray degreaser on my food the next day and wait to see who complains. Turns out, I’m the one who got in trouble for that even though I put a ‘do not eat’ sign in the food.
It means you’re still in consideration.
I know when I’ve hired in the past, if I like the first person I interview I still try to interview at least one more person so I actually have a choice. If I don’t like someone I’ll immediately let them know.
